which will in no way interfere with the discharge of the load from' the car.

A further -olrlect is to provide means which will posit-ively prevent the car fromA tilting' toward the operator and dumpingy the Contents of the ear upon' him.

Other objects of the invention will appear from the following detailed description.

The invention consists Igenerally in various constructions and combinations. all as hereinafter described and particularly point- In the accompanying drawings formingr part of this siieeilication, Figure' l is an end elevation of a car embodyingr my invention, Fig. 2 is a similar View showingthe car tilted, Fig. 3 is a detail View of the device for locking the car body, Fig. 4 is a side elevation of the car.

In the drawings, 2 represents the truck frame, 3 a series of Standards or pedestals mounted at suitable intervals along:I the. eenter line of the car and 4 the car body, pivotally supported on the pedestals 3 at pivotal points 5, there being' a suitable number of these points according to the` capacity of the Car.-

VThe sides of |the car body are open.y to allow it. to discharge its contents upon either side of the ear. and gates are hinged at 6 on each side ot the car body, consisting of plates 7 which close the discharge. openings and have end wings S whichlap by the ends ot the car body on each side and at each end of the car. When the gates are tilted outwardly the plates 7 form eontinuations ot the.V bottom of the car 'body vwhile the wings S will. form continuations of the end -walls thereof, t-hcrebyguiiding and direeting the material discharged from the car body away from the truck frame andwheels, and to a considerable distance from the track. The gates operate quickly,.mov ingr faster than the. tilting body vbylneans of the mechanism hereinafterdescribed, so that under all circumstances the openings at the sides of the car will be unobstructed, the gates tilting on their hinges ahead of the material so that no matter how quickly the car body may be tilted, the gates will vin no way obstruct the. flow of the material therefrom. For the purpose otvcontrolling the movement. of these gates and thetiltingr of the ear l provide rock shafts 'mounted in bearings 10 upon each sideofrthe car, lengthwise thereof. Each 'of theseshafts .has an operating. lever 10', preferably mounted about midway of the shaft; At

suitable intervals-on the shaft.l strilts l1 are arranged, having anti-friction rollers12 at their upper ends which bear on the floorof the car body l and support it securely against premature tilting. Bars 13 arefpivotally vconnected at one end With the upper portions of the struts 11 and exjtend'transveisely of the car and are connected to arms 14 mounted on the rook shafts 9. These arms may be secured to the rock shaftsby any suitable means, and the rock shafts may be made polygonal in cross section to prevent the arms from turning thereon. When- 4the arms andthe bars are in line with 'one another, as indicated in Fig. l, they: will form a togglev mechanism which will -holfd the upright struts at the other side of the car rigidly in their locking position, and as the bars attached to the struts on one Aside of the car are connected to the rock sha-ft on the opposite side lof the'ear it follows that it willbe-impossible for the operai-.torv to dump the contents of theear upon'hirnself. As soon as the struts are removed from one side of the Car the load in the car will cause the body to tilt toward that side assuming that the greater portion of the load is on that `side of the body. pivot, and at that time.

the gale on that side of the ear will be -100 `f5`-pened by the mechanism which l will not' proceed to describe in detail.

Bars 15 are pivotally connected at one end to the wings 8 of the gate on one side of the car and extending across the'sar are pivotally connected at their` opposite ends to the lower ends of links 1G whose upper ends are pivotally connected to the wings on that side of the car. The pivot pins 17 connecting the bars 15 and the links 16 are extending beyond the links and bars and are adapted to fit into seats 18 provided in castings 19 that are mounted on the truck frame. Pins Q0 are slidable in sockets in the cast ings 19 and are adapted to move inwardly over the pins 17 and lock them in the seats 1S. The outer ends of the` pins 9.0 have loops 2l. thereon to receive arms QZmouno ed on the roe-k shafts so that when the shafts are rocked the pins 2O at a predetermined point in the movement of the arms will be. actuated to release the pins 17 and allow the gate on the opposite side of the ear to swing outwardly as the car body tilts with the removal of the support on that side of the car. rlhis movement is indicated plainly in Fig. 2, where the bar l and the link 16 are shown released from the casting 19 and swinging upwardly to allow one of the gates to assume its open position. ,At the same time, as the car body tilts, the links attached to the opening gate will limit its tilting movement, as vindicated lin Fig. 2, though permitting it to swing to a point. where it will be entirely out of thepath of the material flowing from the car before the tilting of the car body is checked. At the same time that the bars and the links 16 are released by the rocking of the shaft, the supports on one side of the car will be Withdrawn so that the car body can. tilt away from the operator and discharge its contents. When the car dumps, the bars 1,5 attached to the gate on that side of the car in which the operator is stationed hold the gate on that side in place and prevent the load in the car from shoving the gate outwardly before the car dumps. As the car body tilts, the gate on the dumping side will swing outwardly and the bars connected with the gate being released at their inner ends, the gate will move faster than the car body and assume theposition indicated by fnll line-s in F ig. 2 when the car body reaches its dumping position. The gate will thus form' an inclined continuation of the floor of the car body and in no way retard the discharge of the material from the car. Willen the material has been discharged, the car body may be swung back to its normal horizontal position. The closing of the gate is caused by the car body coming to its normal position. ln the upright supports or struts should get out ot order the bars attached to the gates will prevent them from tilting until repairs have been made. ln some instances it may be desirable to .wary other material than ore and I may release the' locking bars and links allowing them to as snme the position shown by dotted lines in Fig. l, so that the gates will drop to form horizontal continnations of the car floor; then upon releasing the supports the car body may be tilted in either direction, as desired. In other respects the operation of the car is substantially as heretofore described.
